Cream Cheese Savory Thumbprint Cookies

Preheat oven to 325 F. Grease a baking sheet (9″x12″) with butter and set aside.

For the filling:
Into a bowl, add cream cheese, mustard, onion, salt and olive oil. Stir a little and set aside.

For the dough:
In a large bowl, mix all-purpose flour with salt. Add butter, beaten egg and vinegar, mix until all is combined. The dough must be moist: not too dry nor too humid or sticky. It must be good enough for you to make balls.

Knead dough for 2 minutes. Let it rest for 10 minutes.

Shape dough into small balls (1.5 inch diameter). With your thumb, make an indentation in the top of each cookie.

Then, fill each one with cream cheese filling.

Put each ball on the baking sheet and bake them for 10-15 minutes, until cookies are golden.
